As shown in the accompanying drawings, 1 is the barrel of the gun; the"fore end, so called; 3, the magazine into which the eartridges 16 areplaced, and 12 is the stock oi the gun.

The magazineis made with two side chainbers and a central channel, abovethe upper part of which channel breechebolte is slidable,

and within the lower part and behind the cartridge-chamber 18 the guardand operatinglever 6 movable. The upper end ot' the level' 6 is pivotedto the breech-bolt #t near its front, andan equaliying-link 5 is pivotedto the front lower part ot' the magazine, and the opposite end, which isslotted, as shown, is pivoted to the lever at a pointintermediatebetween its ends.

8 is asafetiY locking-bolthaving'its rear end rl`he slotted connectionbetween the link 5 and the lever 6 allows the lever (3 when iirst movedto open the breech to pulldown upon the link 7 and locking-bolt 8, so asto disengage the locking'diolt from the breech-block before the lever 6conmiences to retract the breech-block. llhe pin which connects thelever (i with the link 5 slides in the slot in the link during' theiii-st portion of the downward movement oi' the lever and until thelockingbolt is disengaged from the breeclrbolt. At'- ter that, the pinin the lever (5 liaving moved to the front end ot' the slot in the link5, the latter serves as a Jfulcrum about which the remainder ot' thedownward movement Oi the lever is eliected and the breech-bolt isrctraeted.

9 is the hammer of the gun, which is force",I back against the tensionof the mainsprii 23 by the rearward movement oi the breedbolt 4, thelower part-ot which engages the head of the hammer, as shown, and whenfully retracted it is engaged by the sear of the trigger 10.

The firing-pin is made in sections c, extend* .ing iongitudinallytln'ongh the breech-bolt #i from the rear to the front end, and the rearend of this firing-pin is in line to be struck by the hammer when itfalls, the front end being in suchposition as to strike and explode thefulminate of the cartridge when the latter is in the barrel of the gun.The tiring-pin channel is so located that itcrosses the lockingrecess 22in the lower part of the breech-bolt, and when the safety-lock 8 iswithdrawn from the breech-bolt by the opening of the breech mechanismthere is no connection between the rear and front p'ortions of thefiring-pin, which are permanently located in the breech-bolt, thuspresenting no danger of explosion by accidentally striking the rear endof the tiring-pin. When the breech mechanism is closed and thelocking-lug 8 of the lock-bolt 8 enters the slot or channel 22, it [illsthis channel, and the section a. of the firing-pin which passes throughthis locking-lug is then brought into line with the parts a of theliring-pin which are in the breech-boltf Under these conditions thesections of the firing-pin are in line with each other, and when thehammer falls upon the rear' end the effect of the blow is communicatedthrough the sections to expiode the cartridge.

The magazine is made, as previously described, with twocartridge-chambcrs 18, l0- cated upon opposite sides oir' the centralchannel,'witliin whichehannel the lever 6 is adapted to swing, so thatthe cartridges are out of iinewith the axis of the barrel when in place.At the bottom of each chamber is a carrier 14 and spring l5, upon which.the cartridges are adapted to rest, and the tendency of this spring isto raise them upwardly, so that as fast as the upper one is removed fromeither chamber the remainder' of the cartridges are raised, so that theupper one is constantly in position to be transferred to the barrel ci'lthe gun by the movement of the breech-action, and when thus transferred-the cartridge-shell lies in a position with the projectile Within thebore 19 of the gun. The spring 15 is secured at the front end by a bolt,as shown at 20, and upon its rear end is acartridge-carrier 14C, uponwhich the lowermost of the cartridges rest. the others standing,essentially, in avertical piane above the same. The springs 15 are'movable in Vertical slots, as shown intransverse section. Upon theouter sides of these slots rare movabie racks 26, having teeth on theirinner faces, and these are actuated by buttons 26a, which projectslightly upon-each side of the magazine, so that they may 'be pressedinwardly by the thumb and finger' of the operator.

This movement forces the toothed inner faces of the catches into linewith t ie carriersprings, so that as the cartridges are placed in thechambers and each one presses the next one down the carrier-springs willenthe rackplates,and will thus be prevented from immediately forcing thecartridges out again. VJ hen the magazines are thus filled, thecartridge eut-eti' 13 may be turned so as to prevent any transfer of thecartridges from either of the chambers of the magazine to the barrel ofthe gun. Under these -conditions single cartridges may be inserted lWhenever the springs, as at 13b.

breech-bolt is retracted and impellcd into the barrel by its forwardmovement. The tops of the magazine-chamber are closed, shown intransverse section, and the intermediate eenw tral portion is normallyclosed by the closing of the breech-bolt. Vvlhcn the breech-boltretracted and the cutoii is turned so as to re lease the cartridges:from one side et' the magazine, they Will be transferred into thebarrel by each reciprocation or' the breech-bolt. The cut-oli consistsof a turnable milled header thumb-piece, and this carries anirregulariyshaped cam 13. l

13 represents plates pivoted to the front of the breech-bolt and pressedoutwardly by Pi ns i3 project upward 5y from the plates 13a and enterthe groove of vthe cam. rlhis groove is so shaped that by turning thecam to a certain position both plates 13 will be drawn inward, so as notto project from the sides of the breech-bolt, and when thus retained thebolt may be reciprocated without moving the cartridges from theirrespective magazine-chain bers. By turning the cam a part of arevolution the pin i3" of one of theplates 13 moves into the wider curveof the cam-groove and the plate may be pressed outward by its spring 13,so that the forward end of the plate wiil he projected into thecorresprnding magazine-chamberbe hind a cartridge when the breech-boltis withdrawn` and When the ibolt is moved forward the plate will engagethe uppermost cartridge in the chamber and advance and transfer it toVthe barrel, no action taking place in the other magazine. N hen onereceiver is exhausted, the cam may be turned a l1alt-r wolution, andthis will release'the plate 13 upon the side of the full magazine andretract the opposite one.

To load the arm, the cut-oti 13 is set, as shown, toA release 13,(right.) 13 springpressed, as shown., and as the breech-bolt iswithdrawn i3 springs inward until the head of top cartridge is passed.lhen it springs outward and engages in rear or'. head of cartridge andpushes it into the chamber in barrei. This can be released until theright magazine is empty. Then by turning i3 halt-round 15 (left) isreleased and 13 (right) is closed, and by turning one quarter-roundi3(right} 13 (left) are closed and the gun can be used as la singleloader. To lill the magazinmthc breechbolt is withdrawn and the carrier,11i pushed down by the finger, the other hand pressing in one or bothknobs onthe toothed racks at the front of the receiver. These racks eng:e the carrier-springs and keep them from push'- ing upward while fillingthe magazine. A slight pressure on each cartridge,willdepress thesesprings, and they can be released when the magazines are full bywithdrawing pressure from the knobs ci' the toothed racks. The tops or'the magazines are closed, and the cartridges are prevented from rollingout into the magazine by the-curved spring i7, which IOO ILO

ts over the top cartridge and which is raised as the cartridge ispressedfrom the magazine into thebarrel.

The pieces 13 have a slight projection or bevel outward at fl in frontet' the breech-bolt. They fit in suitable slots on each side et the rearot' the cartridge-chamber. These projections are so beveled that whenthe parts 13 are projected outward they will stand straight across andproperly engage the cartridges to move them forward.

At the rear of each magazine is a suitablycurved end against which thecartridges slide, and to keep them in line v'ith the are described bythe carrier-spring the cartridge-heads slide in suitable grooves in theside walls of the magazines. This keeps them in line and prevents anyjamming or wedging.

The lextractor 3() is shaped approximately shown in the drawings, andthe front end is hook-shaped'andadapted to engage the fiange of thecartridge-head when the latter has been forced into thecartridge-chamber, and when the breech-bolt is again withdrawn thisextractor acts to draw the cartridge out of the chamber.

`The ejector is shown at 27 and is a spring. It is of bell-crank shapepivotcd at the angle, with one arm extending' under the lower edge ofthe cartridge-head, so that while the other is caught by the lever whenopening the gun a tension is placed upon the spring, and this, inconjunction with the extractor, acts to throw the cartridge-shell upwardand backward and out of the chamber.

The cartridges are guided from their chambers at each side by theconvergently-curved front endsof the outer sides of the magazine, as at3b, and by means of a centrally-pivotcd spring-guide, as at Q8, having'an upwardlyprojecting tin, the cartridges from either magazine areprevented from being forced too far toward the opposite side to enterthe cartridge-chamber on that side of the gun.

The lever is held in place and prevented from falling downward when thegun is closed by the spring-pressed catch` at 50, which lits in 'asuitable opening at 50.
